Burning Questions About a Candle
Source Institutions
In this activity, learners will observe a deceptively simple process: a burning candle.

Rutherford Roller
Source Institutions
In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

Make a DNA Model
Source Institutions
In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.

Styrofoam Traps
Source Institutions
In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.

Tweak Your Beak
Source Institutions
In this activity, learners will explore how different bird beaks work and discover what birds can eat based on their beak shape.

Bee Builders
Source Institutions
In this activity, learners make a model of a beehive using simple materials.

Measuring Earthquakes
Source Institutions
In this activity, learners build their your own seismograph with household materials to document shaking.

Finger Knitting
Source Institutions
In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

Raceways
Source Institutions
In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

Gray Step
Source Institutions
In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

ANTacid: Indicator Paper on an Anthill
Source Institutions
In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

Radiohead
Source Institutions
When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

Ramp it Up
Source Institutions
In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

Water Cycle in a Bag
Source Institutions
In this activity, learners will explore the water cycle by creating a small atmosphere.

Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
